BRS Bulk GFO Granular Ferric Oxide

  • What can I say... By blert on 10/27/2014

    ...never though I would pay so much for a jug of pulverized rust. Maybe I shouldn't have sold that old car... Could have scraped it right off the bumper. LOL! Seriously though... It's good stuff and a decent price when compared to other products.
  • Good Stuff By Christopher on 10/14/2014

    Been using this GFO for over a year and it's good stuff. Keeps my phosphates in check with no problems. Lasts a decent amount of time before I have to change. A little bit of dust to wash out before starting a new batch. No issues with it breaking down as long as you keep the water flow moderate. Works great for me. Thanks BRS
  • Best GFO for the cost! By David on 10/2/2014

    I tried several other products that claimed to clear up phosphate issues but none of them compared to the amazing results I have seen using BRS GFO. It is of the highest quality and the results show it!. The only GFO I will run through my reactor!
  • Great deal By Orlando on 9/29/2014

    I used this mixed with small particle carbon in my reactor, and works perfectly.
  • perfect By Kevin on 8/23/2014

    works like all the other anti phosphate products at what seems like a quarter of the price.
  • Rinse it first By David on 7/30/2014

    I did my homework when it came to adding chemical media in my reef. I have no complaints with this GFO. My Phosphates levels are always nearly undetectable and no algea, just make sure you rinse well before use.
  • Performs well - But needs to be rinsed Very Well By Alex on 7/19/2014

    We used the High Capacity GFO first and it worked great. This time we decided that since we had a large reactor and plenty of space, we could use the GFO that wasn't as compacted to be a little cheaper . It worked for its primary purpose - get the phosphate out. It's just that we had to rinse it with several gallons (5-10) of water to get the dust out and it still left orange dust on the bottom of my sump. I think we will go back to the high capacity stuff after we go through this batch.
  • top notch phosphate removal By swseipel on 7/6/2014

    This has been a great asset to my water treatment system removing phosphate due to my overfeeding my tank
  • Low phosphates! By James on 7/1/2014

    Cleans the water like it says, put it in a reactor and let it work
  • Works Great By Christopher Kirkland on 6/25/2014

    As always works very well, and lasts a long time. Keeps the algae at bay and the PO4 down to levels my SPS like.
